Definitions
- the invention relates to a product, in particular a component a gas turbine, with a base body and one on it arranged thermal insulation layer.
- the invention further relates a method of applying a thermal barrier coating on a Product which can be exposed to a hot aggressive gas is and a basic body, in particular a metallic Has basic body.
- thermal barrier coating system an intermetallic adhesive coating known.
- the Thermal insulation layer system is on a metallic base body applied, especially on a Cr-Co steel for a Aircraft engine blade.
- the basic body is an intermetallic bonding layer, in particular from a nickel aluminide or a Platinum aluminide applied.
- an intermetallic bonding layer in particular from a nickel aluminide or a Platinum aluminide applied.
- To this bonding layer closes a thin ceramic layer made of aluminum oxide to which the actual thermal barrier coating, in particular made of zirconium oxide stabilized with yttrium.
- This ceramic thermal insulation layer made of zirconium oxide has one rod-shaped structure, the rod-shaped stems essentially directed perpendicular to the surface of the base body are. This is intended to improve cyclical thermal load capacity can be guaranteed.
- the thermal insulation layer is by means of an electron beam PVD (Physical Vapor deposition) process deposited on the base body, being with an electron beam gun from a metal oxide body zirconium oxide is evaporated.
- the procedure is carried out in a corresponding device, in which the base body at a temperature of about 950 ° C. is preheated to 1000 ° C.
- the basic body is during the Coating process in the metal oxide beam with a constant speed rotates.
- U.S. Patent 4,405,659 and U.S. Patent 5,514,482 are each Components, in particular gas turbine blades, from a Nikkel or cobalt-based alloy, on each of which a ceramic thermal barrier coating with a stem-shaped structure is applied.
- the average diameter of the stems is here over 2.5 ⁇ m, the layer thickness being approximately 125 ⁇ m.
- the ceramic thermal barrier coating is by means of a EB (Electron Beam) PVD process applied.
- WO 98/13531 A1 describes a component, in particular a gas turbine blade, described which on a metallic Basic body a ceramic thermal barrier layer with a stem-shaped Has fine structure, the mean stem diameter less than 2.5 ⁇ m. That low mean Stem diameter for layer thicknesses used in gas turbine construction of the order of magnitude over 100 ⁇ m is replaced by a reactive Gas flow spattering process reached.
- a ionizable gas passed through a hollow cathode and due the voltages prevailing in the hollow cathode ionize, and thus accelerated towards the inner wall of the hollow cathode.
- the hollow cathode has the coating material on its inner wall, in particular metallic zircon, which knocked out by the ions and towards the surface to be coated Basic body is transported.
- EP 0 139 396 A1 describes a coating system for a Turbine blade known in different surface areas various coatings applied are, depending on that on the turbine blade occurring temperature. This is called between one and a cold end of the turbine blade.
- the different coatings are based on the different Temperature requirements regarding their ductility and their creep behavior especially adapted. You point different chemical compositions. This requires that between adjacent layers be different Composition arranged a transition layer becomes.
- the object of the invention is to provide a product which one hot aggressive gas is exposed, with a load-bearing Specify thermal barrier layer. Another job the invention is a method for coating to specify a product with a thermal barrier coating.
- the first-mentioned object is achieved by a product, in particular a component of a gas turbine, which is exposed to a hot aggressive gas and a body has, solved, on the base body a thermal barrier coating same chemical composition applied which is in a first surface area and in a second surface area different fine structures has, and thus in accordance with the intended Use locally prevailing or expected thermomechanical stresses on the product is trained.
- the two surface areas lie in the same surface plane or surface layer. In particular, they are arranged side by side.
- the thermal barrier coating shows in the surface areas the same in terms of its chemical composition Thermal insulation material.
- the thermal barrier coating can therefore be considered as one A material insulation layer can be called. This has opposite Multi-material insulation layers have the decisive advantage that the problems inherent in a material transfer are avoided. At the same time are different Fine structures the respective surface areas for the expected loads.
- thermomechanical loading in areas with different geometries, especially with regard to surface curvature, convexity or concavity, at an expected same local thermomechanical loading the fine structure in the geometrical different surface areas essentially is executed immediately.
- This special training of Coating is an advantage, especially for curved ones Components that are exposed to a hot gas flow, which to locally different thermomechanical loads leads because the thermal insulation layer locally to the occurring thermomechanical loads, such as temperature and force by impacting particles. hereby the life span of the thermal barrier coating can be targeted influence locally, in particular extend, so that the The service life and the lifespan of the product are extended becomes.
- the thermal insulation layer preferably has a fine structure Ceramic stems on which are essentially normal to the surface of the main body are directed.
- the ceramic stems can have a diameter of a few ⁇ m at a Have layer thickness of up to 100 microns or more.
- a Fine structure with ceramic stems is particularly advantageous because these thermal expansions of the main body can follow cyclical temperature changes without damage.
- the ceramic stems in the first surface area preferably have a smaller average diameter than in the second Surface area.
- the thermal barrier coating in the first Surface area can therefore generally have a finer fine structure than in the second surface area, whereby especially this area with finer fine structure increased Temperatures, in particular temperature changes can withstand.
- the thermal insulation layer in the first surface area which has a higher thermomechanical load when the second surface area is exposed opposite the thermal insulation layer in the second surface area preferably a denser fine structure.
- the product is preferably a component of a thermal Machine, especially a gas turbine, such as a stationary one Gas turbine with the field of application in power plant technology or an aircraft engine turbine.
- the product can do this as a heat shield of a combustion chamber or as a turbine blade, a turbine blade or turbine guide blade, be trained.
- a turbine blade has a leading edge and a trailing edge with opposite between them arranged pressure side and suction side. The leading edge is the most thermally stressed point Turbine blade and also due to the impact there Hot gas also exposed to increased erosion conditions.
- On the suction side and the pressure side are similar locally thermomechanical loads.
